Headlines like this really amuse me. Our industry is so rife with acronyms, and I am still striving for the complete sentence using all acronyms...but I digress. Today my contact at the wireless Home Digital Interface (WHDI) consortium told me that Amimon (maker of wireless HDTV semiconductor products and founding member of WHDI consortium) and SRI Radio Systems GbBH, maker of RF products, are teaming up to develop new RF modules based on the WHDI technology. Their hope is that these new products will find traction in consumer electronics, industrial, automotive, and medical applications.
If you need a brush up on what WHDI is, it is the first standard for wireless, uncompressed HD video delivery throughout the home. It can support delivery of equivalent video data rates of up to 3Gbps (including uncompressed 1080p) in a 40MHz channel in the 5GHz band. Range is beyond 100 feet, through walls, and latency is less than one millisecond. Its founding members are: Amimon, Hitachi, Motorola, Samsung, Sharp, Sony and LG Electronics.
For those of you who were at Mobile World Congress last month, Amimon demonstrated how WHDI is integrated into TI's OMAP4-based Blaze Mobile Development Platform. If you are in Nuremberg this week for Embedded World, you can check out SRI's demonstration of WHDI products in Hall 9, booth 466.
If you've seen WHDI in action or you have an opinion about this standard, please sound off below!
Interesting article, Janine. Thanks for raising the topic. A couple of clarifications... Chiming in as the Chairman of a different standards group, WirelessHD (not WHDI), I'd emphasize that WirelessHD was the first group to launch a wireless, uncompressed HD video standard, preceding WHDI by over a year. And the 1 year has made a huge difference. WirelessHD chose to focus on the 60GHz frequency band because the only way to transmit video over the constrained 5GHz channel was to compress and/or "drop bits" (thereby degrading video quality), which is what WHDI technology does. However, WirelessHD maintains a bit-for-bit accuracy of what was sent versus received, making it truly uncompressed and lossless and superior quality. Further the architecture is such that the cost is comparable and in many cases lower, so products are entering the market at the lowest price points, thus several comments to that effect above.
WirelessHD is also the only standard that has products that support 3D. And it is the only standard that will support future 4K resolutions as well. Last, WirelessHD supports data transmission for high-speed transfer of your content (multi-gigabyte movies and such) from device to device, whereas other standards do not. There is certainly tremendous momentum behind WirelessHD, while other solutions continue to struggle. The recent launch of the Alienware M17xr3 from Dell is a great example of this - an embedded PC solution for WirelessHD!
Thanks again for your coverage of the topic!
Good point - I did some quick looking up on this. I am not sure about WHDI, but WirelessHD does support 3D. The Rocketfish WirelessHD adapters from Best Buy mentioned above is an example of 3D support.
In this area I have mostly seen products based off the WirelessHD standard in action, which is based on the 60GHz technology and am very impressed with the performance (truly uncompressed 1080p video, given the high bandwidth available in this spectrum). Here is the link to the WiHD standard if you want to learn more:
Products based on this standard have already hit the market, see below:
I have also increasingly been hearing about gaming platforms from Dell Alienware which is using the same WirelessHD technology.
This standard looks more promising, with actual products from top CE and PC customers in the market already!
I love Bluetooth. Little did I know, seventeen years ago when I was assigned my first project to write about the origins of Bluetooth and the viking that inspired the name that it would bring so much joy and convenience to my life
The main point of this blog is to point out that there is a major shift in LDMOS technology for cellular applications and the device operating voltage is changing from the current 28V range up into the 48V region.
